Working Document WP.29/2018/148

Proposal to clarify the fuel tank capacity restriction for mono-fuel gas vehicles. The definition of “mono-fuel gas vehicle” was slightly amended between the 06 and the 07 series of amendments to UN R83. This proposal aims to align the definitions across both series in order to avoid divergent interpretations.
Although the reference to a 15 liters tank has always been understood to refer to the nominal capacity of the tank, the use of the term “nominal capacity” in UN GTR No. 19 in several places other than the definition of “mono-fuel gas vehicle” can lead to other interpretations of the definition. The word “nominal” should therefore be inserted into the definition in both series of amendments.

7. The expert from OICA introduced ECE/TRANS/WP.29/GRPE/2018/13 clarifying the basis of the petrol tank capacity restriction for mono fuel gas vehicles. GRPE adopted the proposal.

12. GRPE requested the secretariat to submit ECE/TRANS/WP.29/GRPE/2018/13, Annexes IV, VI and VII and Addendum 1 to the report to WP.29 and the Administrative Committee of the 1958 Agreement (AC.1) for consideration and vote at their November 2018 sessions as draft Supplements 2, 1, 12, 12 and 18 to the 03, the 04, the 05, the 06 and the 07 series of amendments to UN Regulation No. 83 respectively.

Proposal to modify the Constant Volume Sampling system temperature sensor time response requirement.

10. The expert from OICA introduced ECE/TRANS/WP.29/GRPE/2018/18 aimed at modifying the Constant Volume Sampling system temperature sensor time response requirement in UN Regulation No. 83. The Chair of GRPE requested clearer provisions to align with the work performed under the IWG on WLTP. The Expert from OICA presented informal document GRPE-77-31 amending ECE/TRANS/WP.29/GRPE/2018/18. GRPE adopted the proposal as reproduced in Annex VII.

12. GRPE requested the secretariat to submit ECE/TRANS/WP.29/GRPE/2018/13, Annexes IV, VI and VII and Addendum 1 to the report to WP.29 and the Administrative Committee of the 1958 Agreement (AC.1) for consideration and vote at their November 2018 sessions as draft Supplements 2, 1, 12, 12 and 18 to the 03, the 04, the 05, the 06 and the 07 series of amendments to UN Regulation No. 83 respectively.

Proposal to allow the usage of WLTP-based Ki and Deterioration Factors (DF) as well as On-Board Diagnostics (OBD) demos under UN R83. The proposal allows the use of the more robust WLTP and eases testing burdens by allowing manufacturers to use WLTP test results for UN R83.

9. The expert from OICA introduced ECE/TRANS/WP.29/GRPE/2018/15 and ECE/TRANS/WP.29/GRPE/2018/17 aimed at adapting the provisions in UN Regulation No. 83 and UN Regulation No. 101 to allow the usage of WLTP-based Ki and Deterioration Factor (DF) factors as well as On-Board Diagnostics (OBD) demos. The experts from EC and UK proposed minor corrections to ECE/TRANS/WP.29/GRPE/2018/15 that GRPE adopted as reproduced in Annex VI. GRPE also adopted ECE/TRANS/WP.29/GRPE/2018/17.

12. GRPE requested the secretariat to submit ECE/TRANS/WP.29/GRPE/2018/13, Annexes IV, VI and VII and Addendum 1 to the report to WP.29 and the Administrative Committee of the 1958 Agreement (AC.1) for consideration and vote at their November 2018 sessions as draft Supplements 2, 1, 12, 12 and 18 to the 03, the 04, the 05, the 06 and the 07 series of amendments to UN Regulation No. 83 respectively.

Proposal of amendments to:

1. align the definitions for bi-fuel vehicles align with the new definitions in UN GTR 15,
2. amend paragraph 5.3.1.2.4. to recognize that particulate pollutant emissions measurements are no longer limited to compression ignition vehicles,
3. amend paragraph 7.4.4.3. of Annex 7 to correct a typographical error,
4. amend paragraph 3.2.1.of Annex 8 to correct an error originating with UN R83 Revision 3 (2005),
5. amend paragraph 6.5.3.5. to correct a cross-reference error introduced in Amendment 1 (reference should read para. 6.5.3.3. rather than 6.5.3.2.) and should refer to the “annex” rather than the “appendix”.

11. The expert from EC presented GRPE-76-32 proposing to amend the definitions for bi-fuel vehicles and align these definitions with those in UN Global Technical Regulation (UN GTR) No. 15. GRPE supported the intention of the proposal.

12. GRPE agreed to reconsider at the June 2018 session GRPE-76-03, GRPE-76-04 and GRPE-76-32. GRPE requested the experts from OICA and EC to combine the documents in one formal document.

Addendum from GRPE to include amendments to provisions for reagent tank specifications and limits for triggering warning and driver inducement systems to the draft Supplement 7.

82. The World Forum considered the draft amendments under agenda items 4.7.1 to 4.7.5 and recommended their submission to AC.1 for voting, with the following exception: documents ECE/TRANS/WP.29/2018/48/Add.1 and ECE/TRANS/WP.29/2018/49/Add.1 under agenda items 4.7.3 and 4.7.4 had been modified in June 2018 by GRPE, and therefore, should not be taken into consideration for vote at this session.

Proposal from the GRPE secretariat to correct omissions found in document WP.29/2018/148 (proposal for Supplement 8 to the 07 series of amendments) as adopted by WP.29. This document can also be downloaded in marked up .pdf and word versions with tracked changes.

8. The secretariat introduced GRPE-78-10 correcting omissions in ECE/TRANS/WP.29/2018/148 adopted in the November 2018 session of WP.29. GRPE adopted GRPE-78-10 as reproduced in Annex V to the session report.

10. GRPE requested the secretariat to submit Annexes IV and VI of the report to WP.29 and Administrative Committee of the 1958 Agreement (AC.1) for consideration and vote at their June 2019 sessions as draft Supplement 13 and 9 to the 06 and 07 series of amendments to UN Regulation No. 83 respectively. GRPE also requested to submit Annex V of the report to WP.29 and AC.1 for consideration and vote at their June 2019 sessions as draft Corrigendum 1 to Supplement 8 to the 07 series of amendments to UN Regulation No. 83.
